(PCWORLD) Evidence continues to mount that the U.S. government is keen on tracking its citizens.

The FBI has started rolling out its $1 billion biometric Next Generation Identification (NGI) system, a nationwide database of mug shots, iris scans, DNA samples, voice recordings, palm prints, and other biometrics collected from more than 100 million Americans and intended to help identify and catch criminals.

The FBI has been piloting the program with several states and by the time it’s fully deployed in 2014 will have at its fingertips a facial recognition database that includes at least 12 million photos of people’s faces.
